Sound like an old guy stuck in his ways.
I have yet to see any reputable scientist or researcher agree with you.
Any one who knows LEDs and has researched lighting as a career knows LEDs are a far better option. And you are some grumpy guy on a forum... I think I know who I will get my information from.
Man i reckon your spot on about the lights and its proven.
BBQ also has a relevant point that should not be missed.
"I move you all form a more agriculture cannabis based board not one that can't even get soil right and where advertising tells you what to say not experience."
Soil is a nightmare product to grow plants in. So so many variants and problems the book is that thick me feet dont touch the floor if i sit on it.
Here's a thought.
Should forums be split into the many different soil types to give peeps a chance to get it right as what you do in one soil you may not do in another.
Hydroponics is a different kettle and sings from one song sheet. Got a problem. Change the nutrient Problem solved. (pretty much).
Again it's got a bad reputation from idiots who do not now how to use it. Or have built a system wrongly and it does not work so NO HYDROPONICS WORKS and that rep has got around.
Unfortunately we will never change advertisers or advertising. Once growers realise NPK grows plants and pretty coloured bottles do not, then we may start getting somewhere.
